Of the moisture thatcollects in the ordinary straight stem pipe thereare two sources, namely, condensation of oily and aqueous vapors in thetobaccoitself and a certain amount of saliva which may enter themouthpiece. If the saliva be permitted to reach the bottom of the pipebowl it adversely affects the quality of the smoke. the. other hand, ifthe natural condensation from the tobacco itself progresses along thepipe stem to the mouth of the smoker it interferes seriously with theenjoyment of the smoke.

This invention aims to prevent either kind of moisture from moving fromits source to the oppositeend of the pipe stem. Another advantagearising out of this invention is that the smoke in its travel is causedto traverse a longer path than it does in the ordinary pipe stem and inthis longer travel becomes more directly exposed to the cooling actionof the atmosphere so that the smoke is actually considerably cooler whenreceived'into the mouth of the user. I

Other objects and advantagesof the invention relating to its functionsand maintenance will be more fully set forth hereinafter. In the drawinga preferred embodiment of the invention is shown,the single figuredisclosing a pipe made in accordance with this invention and shown incentral vertical section.

The illustrated pipe has abowl i, a stem- 2 and a mouthpiece 3 whichfits snugly into the end of the stem in the manner illustrated and inaccordance with time honored practices in pipe construction. A passage]leading from the mouthpiece through to the bottom of the bowl is alsoshown, being the usual passage commonly found in pipes of this generalcharacter. The stem 2 is provided with an aperture 5 and a secondaperture 6, as shown, into which the opposite ends of a tube 1 arethrust, the fit being merely a snug fit which will amply secure the tubein position and yet permit its removal with reasonable convenience. Theend 8 of the tube terminates in full communication with the passage 4,the boring of the hole 5 being continued until such full communicationis attained. Yet the end 8 of the tube does not obstruct the passage.

The other end 9 of the tube sets down into the passage 6 and is notchedout at II on that half of the tube which faces towardthebowl so thatsmoke from the bowl may flow-into and up through the tube. The extremityI2 of the tube extends into the recess H in the bottom of, the bore 6and blocks the passage 4 so that neither smoke nor moisture may flowstraight through the passage 4 in the pipe stem. The smoke must detourthrough the tube 1 while the condensation coming from the bowl willbedeposited in the recess l3 and in the pipe stem between that point andthe bottom of the bowl. The vertical wall of the end 9 of the tube willact asacon densing surface, particularly by reason of the fact that anyheat imparted thereto by the smoke will be dissipated by conductionrapidly up to the top of the U-shaped tube, thence intothe atmosphere. v

Saliva entering the mouthpiecal of course, cannot fiow through the tube,and will be stopped in the passage by the extremity I2 of the tube. Itmay, of course, collect in the pas sagebetween the apertures 5 and6,'which space serves as a reservoir and saves the smoke from passingthrough such accumulated moisture. The U-shaped tube m'ay readily beremoved from the pipe stem and cleaned with an ordinary flexible pipecleaner and at the same time the horizontal passage 4 may be "cleaned'in the usual manner with a pipe cleaner. The holes 5 and 6, which maybe straight sided or tapered, 30 after removal of the U-shaped tube maybe cleaned easily with wads of cotton or paper. There being no sharpbendsin' the tube it-can be readily cleaned with the well known cottoncovered flexible wire pipe cleaners. Thus no dimculty will beexperienced in keeping-the entire pipe perfectly clean.)

It will be apparentthat the tube 1 may be used with curved stems aswellas. straight stems' The tube 1, by reason of. its position, shape andsize, makes'it convenient'for'the userto slip a finger between the legsof the tube and. .thus readily hold the pipe on the one finger alone. Hecan then use the other four fingers on his hand for handling whatevertools,books or papers may be engaginghis attention at the time.Therefore, when this feature of the invention is desired to beused theshape of the space between the legs of the tube will be dimensioned sothat the finger of the user may be wedged snugly therein. v

The material from which the tube is made may be steel,. aluminum orother appropriate metal easily fabricated into the shape shown or it maybe a'hard rubber composition, Bakelite? sage therethrough connected withthe bottom of the bowl, and a removable U-shaped tube hav ing one openend communicating with said pas sage without blocking the same and theother end communicating with the passage, by means of an opening facingtoward the bowl, a part of the wall of said tube being positioned. toseal said passage between said opening and the mouthpiece, said passagebeing wholly unobstrncted'between the bowl andits openend'exeept bysaid'wall.

2. A.;tpipe including a bowl, stem and 'mouthpiece, a passage. extendingdirectly through the mouthpiece and stem into said-bowl, and a removableU -shaped tube piercing thestem at the top side thereof communicatingwith said passage-fit two longitudinallyseparated points, the end of thetube nearest the mouthpiececpening into the passage without'obstructingthe same while the other end nearer the bowl communicates'with thepassage only toward the bowl and has a wallintersecting the passage toseal 3 s m Said passage being wholly unobstructed betweenthe.bowliandits open end except by wall.

3. A pipe including a bowl and stem, the latter being provided with apassage extending from: the bowl tothefree end of the stem, a removableU- -shapedtube entering the stem, from the-topside thereof through twospaced apart apertures, said apertures being provided in the.

4. A' pipe including a bowl and stem provided I with a passage extendingfrom the bowl longinearest the bowl.

V 5. A pipe including a bowl, stem and mouthpiece provided witha passageextending from bowl longitudinally through said stemand mouthpiece,spaced apart apertures being provided in said stem leading from saidpassage upwardly through the top surface of the stem and in opencommunication with said passage, and a U-shaped7 its ends snuglybnt'reincvably fitted into mid-apertures, the tube 'end'ren'rote from thebowl communicating with the passage without obstructingfit, the' endnearest the having a wall portion thereof traversing lndsmliing saidpassage between the two apertures" and being notched to establishcommunication 1mm the bowl throughihe passagethence the tubeto themouthpiece, said: passage through the stem beingwhollyunobstructed'except by a wall portion of the tube end nearestthe'bowL.
